What is the value ofx in the equation 2(6x+4)-6+2x=3(4x+3) + 1<br> 1<br> 3<br> 4<br> 6
ira [324]

Answer:

x = 4

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

<u>Algebra I</u>

  • Equality Properties
  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define Equation</u>

2(6x + 4) - 6 + 2x = 3(4x + 3) + 1

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute:                                   12x + 8 - 6 + 2x = 12x + 9 + 1
  2. Combine like terms:                   14x + 2 = 12x + 10
  3. Subtract 12x on both sides:       2x + 2 = 10
  4. Subtract 2 on both sides:          2x = 8
  5. Divide 2 on both sides:              x = 4

Vectors! Please help! This is the last question OF MY WHOLE SEMESTER! I've tried it so many times and can't get it right. :(
Feliz [49]

Pictures always help; see the one I've attached for reference.

Call the first vector (from HQ to the supply drop) u and the second vector (from supply drop to medics) v. We then want to find w, the vector from the medics to HQ, which corresponds to the vector -(u + v). (This is because u + v is the vector pointing from HQ to the medics; we're talking about the one in the opposite direction.)

Write the vectors in horizontal/vertical component form:

u = (125 km) (cos 235º x + sin 235º y) = (-71.70 x - 102.39 y) km

v = (75 km) (cos 110º x + sin 110º y) = (-25.65 x + 70.48 y) km

Why these angles?

  • "55 degrees south of west" is 235º; due west is 180º from the positive horizontal axis, and you add 55º to this
  • "20 degrees west of north" is 110º; due north is 90º, so add 20º to this

Add the vectors:

u + v = (-97.35 x - 31.92 y) km

Multiply by -1 to get the vector w:

w = -(u + v) = (97.35 x + 31.92 y) km

The distance covered by this vector is equal to its magnitude:

||w|| = √((97.35 km)^2 + (31.92 km)^2) = 102.45 km

The direction <em>θ</em> is given by

tan<em>θ</em> = (31.92 km)/(97.35 km)  ==>  <em>θ</em> = 18.15º

Total consumption of fruit juice in a particular country in 2006 was about 2.05 billion gallons. The population of that country
Maslowich

Answer:

4.1 gallons per person

Step-by-step explanation:

The total consumption of fruit juice is 2.05 billion

The total population is 500 million

Therefore the average number of gallons fruit juice consumed per person can be calculated as follows

=total consumption/total population

= 2,050,000,000/500,000,000

= 4.1 gallons per person

Can anyone solve this algebra 2 problem? <br> 15^2x-3 = 245<br> Please show work.
DochEvi [55]
15^2x is 225x.  So, we have 225x-3=245.  Adding three to both sides, we get 225x=248.  Dividing by 225, we have x=248/225.
